To find the exterior angle measure we would use the following formula:
![\frac{360~degrees }{number ~of ~sides}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360~degrees%20%7D%7Bnumber%20~of%20~sides%7D%20)
A regular hexagon has 6 sides so we divide:
360/6 which equals 60
So our final answer would be A. 60
the value of r of the geometric series n=11.3(0.8)n-1
![an=11.3(0.8)^{n-1}](https://tex.z-dn.net/?f=an%3D11.3%280.8%29%5E%7Bn-1%7D)
General formula for nth term of any geometric series is ![a_n=a_1(r)^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1%28r%29%5E%7Bn-1%7D)
Here 'r' is the common ratio
a_1 is the first term of the series
Now we compare the given formula with general formula
Compare
with ![a_n=a_1(r)^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1%28r%29%5E%7Bn-1%7D)
The value of r= 0.8
